BOAT.

Application filed J'u1y22,

My invention relates to boats and in particular to the construction of the hull.

It is the object of my invention to provide a boat capable of being produced preferabl in metal in quantities by reason of its simphfied construction and ease of assembly.

In particular, it is my object to provide a frame work of transverse ribs, continuous fore and aft, keel, chine and gunwale members and continuous interleaved body sections.

Referring to the drawings:

Figure 1 is a side elevation of the boat hull embodyingmy invention;

Figure 2 is a section on the line 2-2 looking in the direction of the arrows in Figure 1;

Figure 3 is a section on the line 33 of Figure 1 looking in the direction of the arrows.

Referring to the drawings in detail, 1 designates a right angle metal rib, of which there are a plurality forming the transverse reinforcing members of the boat body.

Mounted on the keel of the boat connected to each of the ribs is a continuously extending bow stem and keel member semi-circular in section, designated 2, having outwardly flaring flanges 3 attached by rivets 4 to the ribs.

On either side chine members 5 are provided attached by the rivets 6 to the ribs and having a chine edge 7. The tops of the ribs are connected together by gunwale mem bers 8 which are semi-circular in section having a flange 9 extending parallel. to the ribs and attached thereto by rivets 10 and an overlapping cap flange 11 overlapping the upper ends of the ribs.

Between the unwale and chine members, there is located a continuous strip of thin metal constituting the hull plate designated 12. A second similar plate designated 13 is located between the chine and the keel members. Thus, with four body vplates, a keel member, two chine members and two gunwale members in addition to the usual transverse ribs, I am able to produce a very strong boat body made of simple shapes and capable of quantity production.

As a matter of practice in a small hull,

1926. Serial No. 124,209.

these body sheets would be about 18 to 22 gauge metal while the longitudinal members would be from 11 to 14 gauge. Due to the difliculties in drawing, I have been unable to show these differences sufficiently exaggerated, but it will be understood that that is my preference in constructing a boat of the smaller type according to my invention.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is L 1. In a boat body, the combination of a plurality of angular ribs, a continuous keel member attached thereto, continuous'chine members attached thereto and continuous longitudinally extending body plate members located therebetween and on the sides thereof.

2. In a boatbody, the combination of a plurality of angular ribs, a continuous keel member attached thereto, continuous chine members attached thereto and continuous longitudinally extending body plate members located therebetween and on the sides thereof, and gunwalemembersf 3. In a boat body, the combination of a plurality of angular ribs, a continuous keel member attached thereto, continuous chine members attached thereto and continuous, longitudinally extending body plate members located therebetween and on the sides thereof, and gunwale members, said gunwale members having flanges overlapping the ends of the ribs.

4. In a boat body, the combination of a plurality of spaced. angular ribs, a continu ous keel member, semi-circular in section, having flaring flanges connected to said rib members, continuous chine members having flanges adapted to be engaged by said ribs,

continuousgunwale members having flanges 7 ous keel member, semi-circular in section, having flaring flanges connected to said rib members, continuous chine members having flanges adapted to be engaged by said ribs, continuous gunwale members having flanges adapted to be attached to said ribs and continuous longitudinally extending body plate members located between said keel, chine and gunwale members, said gunwale members having overlapplng flanges overlapping the upper ends of the rlbs.

In testimony whereof, I affix my 51 gnature.

LOUIS R. RUTHENBURG.
